The ISO 9000 family of standards provides a framework for quality management systems. ISO 9001:2008 is the key standard that specifies requirements for a quality management system that can be certified. It requires organizations to systematically manage their processes to consistently meet customer expectations. The standard is flexible and can be implemented across diverse organizations. Organizations are required to audit their own quality systems and may choose to have independent certification audits to verify compliance, which can help gain clients' confidence and reduce redundant audits.
